I. Thecla of Iconium. The reputed pupil of the Apostle Paul, who is the heroine of the apocryphal “Acta Pauli et Theclae” (cf. APOCRYPHA). Our knowledge of her is derived exclusively from these Acts, which appeared about 180. According to this narrative Thecla was a virgin of Iconium who was converted to Christianity and led to dedicate herself to perpetual virginity by the preaching of the Apostle Paul. Miraculously saved from death at the stake to which she had been condemned, she went with Saint Paul to Antioch in Pisidia where she was thrown to the wild beasts and was again saved from death by a miracle. After this she went to Myra where the Apostle was, and finally to Seleucia where she died. With the consent of Saint Paul she had acted as a “female Apostle” in proclaiming the Gospel. Notwithstanding the purely legendary character of the entire story, it is not impossible that it is connected with an historical person. It is easy to believe that a virgin of this name who was a native of Iconium was actually converted by Saint Paul and then, like many other women of the Apostolic and later times, laboured in the work of Christian missions (cf. Harnack, “Die Mission und die Ausbreitung des Christentums in den ersten drei Jahrhunderten”, 2nd ed., I, 295; II, 58). In the Eastern Church the wide circulation of the Acts led to a great veneration of Thecla. She was called “Apostle and protomartyr among women”. Her veneration was especially great in a number of Oriental cities, as Seleucia where she was buried, Iconium, and Nicomedia. Her cult appeared very early also in Western Europe, particularly in those districts where the Gallican Liturgy prevailed; there is direct proof of this in the fourth century. Her name is given with various topographical comments (Nicomedia, Seleucia, Asia) on several days in the “Martyrologium Hieronymianum”. Thus Thecla is mentioned in this martyrology on 22 February, 25 February, 12 September, 23 September, and 17 November (“Mart. Hieron.”. ed. de Rossi-Duchesne, 24, 36, 120, 124, 144). It seems certain that on all these dates, and probably also on 20 and 21 December, the same Saint Thecla, the pupil of Saint Paul, is meant. In Bede’s Martyrology (cf. Quentin, “Martyrologes historiques du moyen âge”, 93) her name is mentioned with a brief notice taken from the Acts on 23 September, the same date as that on which her feast is given in the present Roman Martyrology. The Greek Church celebrates her feast on 24 September and gives her the title of “Protomartyr among women and equal to the Apostles” (cf. Nilles, “Calendarium utriusque ecclesiae”, I, 283 sq.). See bibliography of APOCRYPHA; HOLZHEY, Die Thecla-Akten, ihre Verbreitung u. Beurteilung in der Kirche (Munich, 1905).

II. We possess historically accurate accounts of the martyrdom of a Christian of Gaza in Palestine named Thecla. According to Eusebius (“De martyribus Palestinen.”, 3) she was condemned to death in the second year of the great persecution (304-05) together with a Christian named Agapius and was torn to pieces in a horrible manner by the wild beasts to which she was thrown. The present Roman Martyrology gives the feast of this saint under thc date of 19 August.

III. The “Martyrologium Hieronymianum mentions a Thecla in connection with a Zosimus among the martyrs whose feast was celebrated on 1 June; these two saints were commemorated at Antioch. Whether this Thecla was a local saint of the Oriental metropolis is not known.

IV. A catacomb of Saint Thecla on the Via Ostiensis, not far from the burial place of Saint Paul, is mentioned in the seventh-century itineraries to the graves of the Roman martyrs. A church stood on this spot on a hill over the catacomb where the body of the saint rested. Saint Thecla must be regarded as a Roman martyr. Armellini believes that he has found the cemetery of Saint Thecla (cf. Marucchi, Les catacombes romaines”, Rome, 1903, p. 91 sqq.).

V. The Martyrology of Saint Jerome mentions under 31 May (69), in connection with two martyrs buried on the Via Aurelia, a group of martyrs named Tertulla, Lupus, Justa, and Thecla. It is very possible that besides the Saint Thecla buried on the Via Ostiensis another Roman female martyr bearing the same name was buried on the Via Aurelia. Still we have no further account of this group of martyrs, and just as little of a number of Roman martyrs, among whom the name of a Thecla also occurs, that are given under 26 March in the present Roman Martyrology.

VI. In the “Martyrologium Hieronymianum” (58, 78) a long list of the names of African martyrs is given under the dates of 10 May, l3 and 14 June, and each time a Thecla is mentioned. Nothing further is known of this saint. In the legend of the twelve brothers and martyrs, Donatus, etc. (cf. Acta SS., Sept., I, 138-41), the parents of the brothers are called Boniface and Thecla, and these two are also given in the present Roman Martyrology as martyrs under 30 August. Apart from the purely legendary Acts just mentioned nothing is known of them. VII. In the “Acts of Saint Hermagoras”, which are equally legendary (Baronius, “Martyr. Romanum cum notis Baronii”, Venice, 1609, p. 494) a Saint Thecla of Aquileia is mentioned together with several other martyrs who are only known through this legend. Their feast is observed on 3 September.
